New to Java

I have been at this for two days now. When I complie I get: cannot find symbol method(java.lang.String)

I also found out that the reason that I am getting that complier error is because the argument needs to be a courseSection object. Can someone point me in right direction on how to convert the String into a CourseSection object? Thanks.

Scanner fileReader = new Scanner(
				new FileInputStream("class-schedule.txt"));		
								
				 
				ArrayList<CourseSection> schedule = new ArrayList<CourseSection>();
				
				
					//for(int index = 0; index < schedule.size(); index++)
					while(fileReader.hasNextLine())			
				
				schedule.add(fileReader.nextLine());
